Stony Island(1978)

Richie Bloom, the only white kid on the block, forms an R&B band with his best friend, Kevin. With the help of their mentor, aging sax legend Percy, they pull together a funky supergroup. Despite few resources and heavy losses this resilient group of dedicated musicians, armed only with wit, sleight of hand and outrageous Chicago bravado must come together to finally make their smash debut.
